chainsuck

An annoying ride-ruiner, chainsuck is when the small or middle chainring snags the chain beneath the chainstay and pulls it upwards (where the "suck" part of chainsuck comes from). This sometimes jams it between the chainring and the chainstay bringing pedaling to a grinding halt. Chainsuck is usually caused by mud, worn components and/or lack of lube.
